Okay, but do you expect the crow to colonize the universe?
LOL, maybe in several millions years, who knows. The point is there are other intelligent species on this planet besides humans, however very primitive. I for one, put my bet on life outside of earth, both intelligent and non intelligent, and I feel the universe is far to vast for anyone on this planet to say the chances of intelligent life out there are small, if at all. Just because we have no proof at this point, means little, IMO.
